Abstract: SURGICAL INSTRUMENT HAVING SELF-REGULATED ELECTRICAL INDUCTION HEATING OF ITS CUTTING     EDGE AND METHOD OF USING THE SAME     Abstract of the Disclosure The cutting edge of a scalpel blade is electrically heated by induction of circulating currents in the internal structure of the blade near the cutting edge.  Selective heating of regions of the cutting edge that are locally cooled by contact with tissue during surgical cutting is pro-vided by constructing the blade of ferromagnetic materials that have a Curie point in the operating temperature range and that provide large increases in permeability for tempera-ture decrements below the Curie point.

Abstract: Abstract:            A process for the conversion of caronaceous materials containing sulphur to an essentially sulphur-free combustible gas by gasification, comprising partially gasifying the carbonaceous material in a first circulating fluid bed by supplying to said zone adjusted flows of the carbonaceous material, finely-divided CaO-containing material and steam, separating soled materials from the flow of gases and solid materials leaving said reaction zone, subjecting an adjusted fraction of the flow of said solid materials to separation of ashes and sulphur purification and then returning the flow to the reaction zone, transferring the rest of the solid materials to a second circulating fluid bed, wherein the solid materials by partial combustion with an ad-justed flow of gases containing molecular oxygen is heated to an overtemperature which is adjusted by controlling the content of oxygen of the gas in such a way that the materials after separation from the reaction gases and recirculation to the first fluid bed covers the heat requirement for the gasification therein. The invention also covers an apparatus for carrying out said process.

Abstract: ABSTRACT OF THE DISCLOSURE      A pilot valve mechanism for controlling the flow of a pressure medium responsive to predetermined variations in a pressurized system.  The pilot valve mechanism is constructed in such manner that a plurality of pilot valves may be connected in assembly and may be operative to shut down operation of a flow system responsive to sensing of pressure that are above or below a predetermined range of operating pressure.      Each of the valves may include a shuttle valve mechanism capable of interrupting fluid communication between the inlet and outlet of the pilot valve mechanism or between the outlet and vent of the valve assembly, depending upon the position of a shuttle valve actuating piston that is proportionally movable responsive to variations in the pressure that is sensed by the pilot valve mechanism.  Movement of the piston and shuttle valve to the various positions thereof may be controlled by an urging means that  may be adjustably preset for a particular high or low pressure.  The shuttle valve may incorporate annular end seals that are retained in assembly with the shuttle valve and engage annular seal sur-faces, defined within the valve body of the valve assembly, to control fluid communication between the various ports.  Slight movement of the end seals of the shuttle valve away from the annular sealing surfaces affords substantial cross-sectional flow area for large volume flow, thus providing for rapid pressure responsive actuation.  Utilization of piston sealing elements having low friction characteristics and utilization of a tension spring for urging the shuttle valve and piston between operative positions thereof, facilitated accurate operation of the pilot valve mechanism at relatively narrow pressure differentials.

Abstract: ABSTRACT OF THE DISCLOSURE         This is a process for the preparation of sterile culture media in unit dosages in which cer-tain of the ingredients are increased prior to irra-diation of the unit dosages so that the irradiated specimen gives culture results comparable to con-ventionally sterilized media.  This process permits the preparation of the culture medium dispensed in specially designed containers and manufactured and packaged under non-sterile conditions.  These pack-aged medium may then be sterilized using a one-step sterilization.  Some of the ingredients are increased in quantity so that the irradiated medium of equi-valent quality to the conventional media, is ob-tained.  Furthermore, we have found that increasing the pH factor of the medium prior to irradiation results in a pH of desirable level after irradiation once again producing a sterile medium of equivalent quality to conventional media.

Abstract: ABSTRACT OF THE DISCLOSURE.           In the calcination of petroleum coke or the like in a rotary kiln, utilizing controlled air supply intermediate the ends Or the kiln to burn removed volatiles and thereby generate all or nearly all of the heat required, highly ef-fective control procedure includes establishing and repeatedly re-establishing target values for temperatures of exit gas and discharging product respectively at opposite ends of the kiln, such target temperatures representing conditions of desired position of the calcining zone and desired physical character of the calcined product which is achieved by proper maximum temperature in said zone.  The procedure further includes ad-justing one or more of the variables of combustion air supply, RPM of the kiln, and green coke feed rate so as to keep the end temperatures at target value.  Preferably, only two vari-ables are controlled in order to follow the updated target values, and the procedure also includes adjustment of one or both of such selected variables in order to compensate, when necessary, for changes in the other variable. Efficiency, economy, and unusual facility and reliability of control are achieved.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved x-ray or other ionizing radiation detector includes an array of adjacent cells consisting of alternately-disposed oppositely-polarized electrodes and guard electrodes and insulators between them.  Uniform spacing between electrodes and close control of the overall length of the array are achieved by depositing viscous resinous adhesive at selected location between the electrodes and insulators during assembly.  Groups of cells (i.e. subassemblies) are formed in this manner by assembling the electrode elements and insulators in proper sequence in a form or die which has a radius of curvature, either finite or infinite, conforming with that desired for the detector array.  The subassemblies are baked to cure and solidify the adhesive and maintain the pieces as a unit.  The subassemblies are then joined to others with similar adhesive to form the entire detector array. The whole assembly is then heat-cured and becomes a unit which can be mounted in a gas-filled hollow chamber of the detector assembly.  The configuration of the electrodes is such that the active electrodes, such as the anode and cathode electrodes, can be supported in electrical isolation from the chamber.  The electrodes are also shaped so that those which operate at ground potential can contact the chamber wall and provide support for the entire array.

Abstract: ABSTRACT            The temperature of the surface of a body, such as a continuously cast strand, is measured by apparatus comprising an axially hollow shaft of substantially cylindrical shape, and means for optically scanning the said surface through the inter-ior of the shaft. The scanning means is optically connected with a pyrometer.  The rear end of the shaft is connectible to a con-trol motor for rotating or oscillating the shaft about its axis.          The front end of the shaft has a head supporting scrapers for cleaning the said surface and has a peripheral groove receiving a locking ring.  The head is removable, axially hollow, and coaxial with the shaft.  The scrapers project from its front face.  Arms substantially parallel to the axis of the shaft pro-ject from the rear face of the head and are received by longi-tudinal slots in the shaft.  The arms have such a configuration that, when the rear face of the head is positioned against the front face of the shaft, the free ends of the arms are disposed with play in the longitudinal slots and have external overall radial dimensions greater than the internal dimensions of the locking ring and are at a greater distance from the front end of the shaft than is the locking ring.
